''Luckily nothing really happened because I reacted fast. If another person had got in the car and hadn't had training it could have resulted in something much more dire.''

The performer, who works for Burnt Out Theatre, said she wanted to turn the experience into something more positive, particularly after negative publicity surrounding her parents - former energy secretary Huhne and his ex-wife Vicky Pryce.

They were both jailed for eight months for perverting the course of justice after Pryce revealed that she had taken speeding points on the disgraced MP's behalf.

Miss Huhne said: ''There has been so much publicity around my family and it's been negative, so I wanted to use this horrible experience to raise awareness and turn it into something positive.''

She also warned against taking unlicensed cabs.

''That's the first time I had ever used a non-licensed cab,'' she said. ''However close you are to home, however safe you feel, you must never get in those cars. They are just touters.
